Large, prominent subpleural bullae. Spontaneous pneumothorax often results from rupture of such lesions. Honeycomb fibrosis is present in the subpleural lung parenchyma. In emphysema the spaces resulting from alveolar wall destruction have thin, delicate walls without intervening fibrosis and resemble the appearance of a spider web.
When the subpleural bullae are significant, the emphysema is called bullous emphysema. Bullae can become extensive and combine to form giant bullae. These can be large enough to take up a third of a hemithorax, compress the lung parenchyma, and cause displacement. The emphysema is now termed giant bullous emphysema, more commonly called ...
Subcutaneous emphysema can be caused by medical procedures and medical conditions that cause the pressure in the alveoli of the lung to be higher than that in the tissues outside of them. [4] Its most common causes are pneumothorax or a chest tube that has become occluded by a blood clot or fibrinous material.
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
In the lungs, emphysema involves enlargement of the distal airspaces, [2] and is a major feature of chronic obstructive pulmonary disease (COPD). Other pneumatoses in the lungs are focal (localized) blebs and bullae, pulmonary cysts and cavities. Pneumoperitoneum (or peritoneal emphysema) is air or gas in the abdominal cavity, and is most ...
A rift appeared to open Sunday between some of President Donald Trump’s agency heads and Elon Musk, the billionaire tasked with reforming the federal government, over Musk’s demand that all ...
Bullectomy is a surgical procedure in which dilated air-spaces or bullae in lung parenchyma are removed. [1] Common causes of dilated air-spaces include chronic obstructive pulmonary disease and emphysema. Patients with giant bullae filling half the thoracic volume and compressing relatively normal adjacent parenchyma are recommended for ...
White House press secretary Karoline Leavitt said the mystery drones flown across New Jersey in late 2024 were "authorized to be flown by the FAA" in the first press briefing of President Donald ...
